Just a little episode of Eren getting drunk, in which absolutely nothing happened lol. For a 15-page doujinshi this one felt like it didn't have much real content at all even though its length is actually the average for doujinshi in general. I guess part of the reason for that is the disproportionately long space given to the less important introductory and conclusion scenes compared to what was supposed to be meat of the book which felt even shorter than it already was as a result.
